双通道前导1预判模块的全定制版图设计与验证

Full-custom layout design and simulation of a double path leading-one prediction circuit

前导1判断模块是浮点加法运算中不可缺少的部分,在运算结果产生之前就对运算结果进行预测的方式叫做前导1预判,相应的电路叫前导1预判电路。经过改进的双通道前导1预判电路与单通道运算结构相比具有更高的运算速度,而全定制的版图设计方法具有减小单元面积和时延的优点,用全定制版图设计的方法来设计双通道前导1预判模块,能够进一步提高其性能。

The leading-one prediction is part of the floating point adder.The leading-one prediction algorithm is based on leading-one prediction. The position of the loading-one can be predicted by two paths, and for some operators, the speed of operation can be accelerated and the power consumption can be lower. The full-custom layout design can potentially maximizes the performance of the circuit, and minimizes its area.
